Research notes for these ingredients
Niacinamide
In 50 women aged 40–60, a moisturizer with 5% niacinamide improved several visible signs of aging over 12 weeks compared with its base. The authors were affiliated with P&G.
Bissett et al., 2004 · controlled facial study ↗This was one formula and a specific study population. It does not establish the same effect for every niacinamide product or show that a higher percentage is better.
Hyaluronic acid
A four-week trial on the legs of 36 older adults found higher hydration with a low-molecular-weight HA lotion than a high-molecular-weight lotion or the base. Water loss and symptom scores did not differ significantly.
Muhammad et al., 2024 · randomized trial ↗A leg study in older adults cannot establish facial results for products with different formulas or use sites. Molecular weight, concentration and the whole formula matter.
Ceramides
A 28-day trial in adults with moderate eczema studied a ceramide-rich cream and cleanser together. Hydration and water-loss measures improved; eczema severity did not differ between groups. The study had manufacturer involvement.
Spada et al., 2021 · randomized regimen study ↗This tests a complete two-product regimen, not isolated ceramide NP. It does not prove that any ceramide cream treats eczema.

TWO US FORMULAS / TWO STARTING POINTS
Anua azelaic acid or niacinamide/TXA serum: what is different?
Start with the concern you want to address. Anua positions the azelaic serum for visible redness and blemish care, and the niacinamide/TXA serum for dark spots and uneven-looking tone. Those purposes overlap; they do not establish which product will work better for you.
Swipe across the table to read both products. With a keyboard, focus the table and use the arrow keys.
| What changes | Azelaic Acid 10 Hyaluron Redness Soothing Serum → | Niacinamide 10 TXA 4 Serum → |
|---|---|---|
| Disclosed actives | 10% azelaic acid | 10% niacinamide · 4% tranexamic acid · 2% arbutin |
| Brand's stated focus | The look of redness and blemish-related marks | The look of dark spots, dullness and uneven tone |
| Official starting directions | Begin with 1–2 drops, 1–2 times a week. Increase gradually, up to twice daily, as directed. | A few drops on the areas you want to address, morning and night. |
| Routine position | Between toner and moisturizer; SPF 30+ in daytime | Before moisturizer; SPF 30+ in daytime |
| Source | Anua US azelaic serum · ingredients and directions ↗ | Anua US niacinamide/TXA serum · ingredients and directions ↗ |
The azelaic serum also lists niacinamide and betaine salicylate. Anua does not state their percentages on that product page, so the two bottles are not simply “azelaic acid versus niacinamide.”
The linked pages do not report a direct comparison of these two formulas. The percentages are label information, not a potency score or a reason to combine the products. Follow the directions on the version you buy.
Open these two serums in the ingredient comparison →What do the 10, 4 and 2 percentages refer to?
Anua states 10% niacinamide, 4% tranexamic acid and 2% arbutin. The ingredient list names both Arbutin and Alpha-Arbutin, but does not divide the stated amount between them. The 2% figure cannot be relabeled as 2% alpha-arbutin.
Apply a few drops to areas of concern before moisturizer, morning and evening. The daytime directions call for SPF 30 or higher.
| Ingredient | Published amount |
|---|---|
| Niacinamide | 10% |
| Tranexamic Acid | 4% |
| Arbutin | 2%; amounts of Arbutin and Alpha-Arbutin are not separately stated. |
Questions about this product
Does 2% arbutin mean 2% alpha-arbutin?
The official description says 2% arbutin. Arbutin and Alpha-Arbutin both appear in the ingredient list, without separate percentages. The published figure therefore does not establish 2% alpha-arbutin.

Products with overlapping ingredient lists
Calculations use complete ingredient lists for the stated market and product version. Listed names do not establish concentrations, equivalent effects or allergy suitability.
Explore products in the same use group with overlapping ingredient lists, then compare their texture, directions and ingredient differences.
How are candidates selected?
Candidates share the page’s language, market context and use group and have a complete ingredient list available. Names are normalized for spacing and reviewed synonyms; duplicate names count once.
The default order divides shared names by all distinct names across both lists: 10 shared names out of 20 distinct names gives 10 ÷ 20. You can instead order by the number of shared names. Up to five candidates are shown.
Ingredient overlap does not establish equivalent effects or a cheaper substitute. Concentrations, ingredient order, finished-product tests and feel are not part of this calculation. Missing lists are not treated as missing ingredients.
